Safety Precautions Refer to Safety Precautions for All Limit Switches. CAUTIONS Make sure that the antenna does not come into contact with the human body, otherwise an electric shock may be received. Precautions for Correct Use Mounting Do not tighten the nuts with excessive force. The maximum permissible tightening force of each nut with a washer is 29. N m. Mounting Hole Dimension Antenna <Shape and Extension> If a metal plate is used as an antenna by connecting it to the built-in or separated antenna of the, the surface area of the metal plate must be 200 cm 2 maximum (Fig. 1). The antenna can be extended, provided that the total length of the antenna is 1 m maximum (Fig. 2) and that the bottom of the antenna is at least 10 cm (Fig. 3) away from the ground. Refer to the illustrations below The may be damaged if the antenna is excessively large or heavy or if the antenna is used in locations with excessive vibration or shock. Be sure to check the locations before use. Fig. 1 Metal plate 200cm 2 max. Fig. 2 1 2 6 5 Fig. 3 1 m max. 10 cm min. Grounding of Antenna and Sensing Object 18.5 +0.5-0 dia. <Size of Sensing Object> Grounded Object If the sensing object is the following grounded conductor, its size will not affect the operation of the. Check for the presence of insulators sticking to the sensing object or the corrosion of the sensing object, however, so that the ground resistance will not exceed 3 kω. 3 1+ --- 6 1 m Ground <Parallel Arrangement> If there are multiple s are located in parallel, make sure that the distance between adjacent antennas is at least 3 cm. 3 cm min. Contact with Grounded Conductor The sensing object is equivalently grounded through ground resistor R. 3 cm min. Grounded conductor R: 3 kω max. The sensing object must not come into contact with the human body Non-grounded Object If the sensing object is the following non-grounded conductor, the will operate if the capacitance between the sensing object and the ground is 30 pf or more. The larger the surface area of the sensing object is, the higher its capacitance will be. The shorter the distance between the sensing object and the ground is, the higher the capacitance will be. Furthermore, the capacitance greatly varies with the ground condition (e.g., dry sand, concrete, or wet soil). Contact with Non-grounded Conductor The sensing object is equivalently grounded through capacitor C. 30 pf min. C C: 30 pf min. 3 kω max. Non-grounded conductor R <Conditions of Sensing Object> The detection of conductors (e.g., iron, stainless steel, aluminum, and brass objects) poses no particular problem. A conductor coated with paint cannot be detected, however, because there is no electrical continuity between the antenna and the conductor. Non-conductive objects (e.g., plastic, ceramic, glass, and cloth objects) can be detected by grounding them indirectly. (Refer to Application Examples on page 1.) Generally, the conductor will be detectable if the ambient humidity is 60% to 70%RH and the surface area of the conductor is approximately 300 500 mm. Maintenance Make sure that the portion of the antenna that comes into contact with sensing objects is free of oil, dirt, or rust, or any other insulator. Otherwise, the will not operate. The degree of protection of the is IP67. The cannot be, however, used in the water or oil. Locations with Sprayed Water or Oil The may malfunction in locations where the is frequently exposed to sprayed water or oil. Especially, the may malfunction more frequently if it is exposed to sprayed watersoluble cutting oil. In such locations, be sure to take appropriate measures to protect the from oil and water. Wiring and Connections Be sure to wire the correctly according to the color of each cord. Incorrect wiring may damage the internal components of the or the may malfunction. A maximum of two models can be connected in series provided that to 20 V is supplied. DC models cannot be connected in series. to 20 VAC Be sure to supply power to the via the load. If power is supplied to the directly, the fuse will blow. Power source If there are wire power lines or high-tension lines close to the cable of the, be sure to wire the cable of the away from power lines or high-tension lines or lay the cable in an exclusive, shielded conduit. Remove the caution label on the end of the cable before wiring the cable. 6
-1A@0 (AC Models) Be aware that the -1A@0 not in operation has a leakage current of approximately 2 ma. Especially, if the load is a relay with a current flow of 10 ma or less, a reset failure may result due to the residual voltage. Therefore, connect a bleeder resistor as shown below so that the residual voltage will be less than the reset voltage of the load. Bleeder resistor R AC power supply Vs The bleeder resistance and permissible power are obtained from the following formula. Vs Vs 2 R 10 I (KΩ) P> R (mw) P: W number of bleeder load (Practically, the wattage must be a few times larger than the obtainable value.) I: current (ma) If a DC relay or DC counter is used as a load connected through an electronic timer or current rectification circuit, pay the utmost attention so that the leakage current of the AC model will not cause the load to malfunction. Others Do not disassemble the, otherwise the internal wiring will be damaged and the will fail to operate. The sealing of the uses nitrile butadiene rubber (NBR), which is highly oil resistive. If exposed to some types of oil or chemical indoors or outdoors, however, the NBR may deteriorate. Contact your OMRON representative for details. When mounting the antenna to the, be sure to tighten the antenna to a torque of 0.39 to 0.83 N m. If the antenna is not tightened securely, the built-in contact may break. If an appropriate antenna is mounted to a free attachment model, hold the nut on the outer side with a wrench so that the nut will not move. Then tighten the nut on the inner side within a torque range of 0.78 and 1.18 N m. Direction of turn Antenna Wrench Sensitivity Adjustment The sensitivity of the can be adjusted by turning the adjuster on the rear side with a flat-blade screwdriver. The sensitivity increases by turning the adjuster clockwise (max. 30 pf) and decreases by turning the adjuster counterclockwise (min. pf). SENSI Set point Be sure to turn the adjuster with a torque of 0.08 N m or less. If excessive torque is applied, the adjuster will break. Grounding <For DC and AC Models> In order to maintain the operational reliability of the, be sure to ground the blue or black wire of the power cable. (Refer to Output Circuit Diagram on page.) Operation may fail if the is not grounded. <DC Models> The service power supply of the PC (Programmable Controller) is not available to the -1D@0. The negative line of the service power supply of the PC is not grounded. Therefore, the may not operate. Furthermore, if the negative line of the service power supply is grounded, the noise resistance of the PC will drop. <AC Models> Provided that single-phase 200 V is supplied to the -1A@0, if one phase is grounded, the power supply will be short-circuited and a machinery breakdown will result. Use an isolating transformer and ground the secondary side of the transformer instead. In the above case, be sure to ground the secondary side, otherwise the may not operate.
